Porter-Cable CFFR350C - Manual (Page 12)

Drain Valve: The
drain valve is located
at the base of the air
tank and is used to
drain condensation at
the end of each use.
Check Valve: When the air
compressor is
operating, the
check valve
is "open",
allowing
compressed
air to enter
the air tank.
When the
air compressor reaches "cut-out"
pressure, the check valve "closes",
allowing air pressure to remain inside
the air tank.
Pressure Release Valve: The
pressure release
valve located on
the side of the
pressure switch,
is designed to
automatically
release
compressed
air from the
compressor head
and the outlet tube when the air
compressor reaches "cut-out" pressure
or is shut Off. The pressure release
valve allows the motor to restart freely.
When the motor stops running, air will
be heard escaping from this valve for a
few seconds. No air should be heard
leaking when the motor is running
or after the unit reaches "cut-out"
pressure.
Motor Overload Protector (not
shown): The motor has an automatic
reset thermal overload protector. If
the motor overheats for any reason,
the overload protector will shut
Off the motor. The motor must
be allowed to cool down before
restarting. The compressor will
automatically restart after the motor
cools.

Check Valve
Before First Start Up
Risk of Unsafe
Operation. Serious
damage may result if the following
break-in instructions are not
closely followed.
This procedure is required
before the
air compressor is put into service and
when the check valve or a complete
compressor pump has been replaced.
1. Make sure the On/Auto/Off lever
is in the "Off" position.
2. Plug the power cord into the
correct branch circuit receptacle.
(Refer to Voltage and Circuit
Protection paragraph in the
Installation section of this
manual.)
3. Open the drain valve (counter-
clockwise) fully to permit air to
escape and prevent air pressure
build up in the air tank during the
break-in period.
4. Move the On/Auto/Off lever
to "On/Auto" position. The
compressor will start.
5. Run the compressor for 15
minutes. Make sure the drain
valve is open and there is
minimal air pressure build-up in
tank.
6. After 15 minutes, close the drain
valve by turning clockwise. The
air receiver will fill to "cut-out"
pressure and the motor will
stop.
The compressor is now ready for use.

Air Intake Filter (not shown): This
filter is designed to clean air coming
into the pump. This filter must always
be clean and ventilation openings free
from obstructions. See "Maintenance".
